[0028] With reference to Figures 1 to 4 The present embodiment provides a dispensing head mechanism 200, which can be connected to a mechanical arm 120 of a dispensing machine 100. The dispensing head mechanism 200 includes a connecting piece 210 and a dispensing seat 220. The connecting piece 210 is connected to the mechanical arm 120, and the dispensing seat 220 is connected to the connecting piece 210. A dispensing needle 240 is detachably connected to the bottom of the dispensing seat 220. When the dispensing needle 240 is blocked, the dispensing needle 240 can be disassembled and replaced, avoiding the need to disassemble the entire dispensing head mechanism 200, and saving disassembly time and cost.

[0029] The connecting piece 210 can be in a columnar shape, and an upper and lower through glue inlet hole 211 is formed in the connecting piece 210. The top opening of the glue inlet hole 211 is used to connect a glue inlet pipe (not shown in the figure). It should be noted that between the top opening of the glue inlet hole 211 and the glue inlet pipe, a flow valve and an electromagnetic valve can be connected. The flow valve is used to control the amount of glue flowing into the glue inlet hole 211, and the electromagnetic valve is used to control the start and stop actions of the glue inlet. The flow valve and the electromagnetic valve are electrically connected.

[0030] The connecting piece 210 is provided with a plurality of through holes penetrating through two side faces, the through holes are not communicated with the glue inlet hole 211, the connecting piece 210 can be connected with the mechanical arm 120 by penetrating through the through holes by fasteners. The mechanical arm 120 can move in three directions of X axis, Y axis and Z axis.

[0031] The glue dispensing seat 220 is provided with a main flow cavity 221, the main flow cavity 221 is communicated with the glue inlet hole 211. The top surface of the glue dispensing seat 220 is provided with a boss 223, the bottom of the connecting piece 210 is connected with the boss 223 by fasteners. The boss 223 protrudes from the top surface of the glue dispensing seat 220 and has a certain thickness, the fasteners penetrate through the through holes in the bottom of the glue dispensing seat 220 and are locked on the boss 223, the boss 223 is arranged to avoid the fasteners penetrating into the main flow cavity 221. The boss 223 is provided with a connecting hole 224 for communicating the glue inlet hole 211 and the main flow cavity 221.

[0032] The bottom of the glue dispensing seat 220 is provided with a glue outlet hole 222, the glue outlet hole 222 is communicated with the main flow cavity 221, and the glue outlet hole 222 is detachably connected with the glue dispensing needle 240. The inner diameter of the glue outlet hole 222 is matched with the outer diameter of the glue dispensing needle 240, and the glue dispensing needle 240 is inserted into the glue outlet hole 222. It should be noted that a clamping groove (not shown in the figure) can also be arranged on the glue dispensing seat 220 and located at the periphery of the bottom of the glue outlet hole 222, and a clamping part is arranged on the glue dispensing needle 240, so that the glue dispensing needle 240 and the glue dispensing seat 220 are detachably connected through the cooperation of the clamping groove and the clamping part.

[0033] The glue outlet hole 222 can be provided with a plurality of glue dispensing needles 240, and each glue outlet hole 222 is inserted with a glue dispensing needle 240. Liquid glue can enter the glue inlet hole 211 from the glue inlet pipe, then be distributed to each glue outlet hole 222 through the main flow cavity 221, and finally flow out from the glue dispensing needle 240. The plurality of glue dispensing needles 240 correspond to the positions to be dispensed on the module one by one, so that the glue dispensing head mechanism 200 only needs to be moved to the specified position by the mechanical arm 120 in advance, and the glue dispensing needle 240 can correspond to the positions to be dispensed on the module one by one, thereby saving the time required for the mechanical arm 120 to drive the glue dispensing head mechanism 200 to move during each dispensing process. At the same time, it can also be possible to avoid the delay of electrical signals during the operation of the mechanical arm 120, which causes the glue to be dispensed in advance, resulting in errors in the dispensing position and affecting the quality.

[0034] Reference Figures 1 to 4 The glue dispensing seat 220 includes a detachably connected upper cover 225 and a bottom plate 228, and the main flow cavity 221 is arranged between the upper cover 225 and the bottom plate 228.

The bottom wall forming the second recess 229 is horizontally arranged, so that the liquid adhesive flowing into the main flow cavity 221 can flow to each glue outlet hole 222 more uniformly.

[0036] The upper cover 225 and the bottom plate 228 can be connected by fasteners. When the glue inlet hole 211, the connecting hole 224, the main flow cavity 221 and the glue outlet hole 222 are blocked, the upper cover 225 and the bottom plate 228 can be separated by disassembling the fasteners, so as to facilitate cleaning of the blockage. A sealing ring (not shown in the figure) can be arranged between the periphery of the upper cover 225 and the periphery of the bottom plate 228, so as to prevent the liquid adhesive from leaking from the periphery of the glue dispensing seat 220.

[0037] The bottom surface of the upper cover 225 is provided with a plurality of first support columns 227, and / or the top surface of the bottom plate 228 is provided with a plurality of second support columns 230. The plurality of first support columns 227 correspond to the plurality of second support columns 230 one by one. Threaded holes are arranged on the first support columns 227 and the second support columns 230. The fasteners can pass through the threaded holes of the first support columns 227 and be locked and connected in the threaded holes of the second support columns 230. The total height of the first support columns 227 and the second support columns 230 is lower than the thickness of the main flow cavity 221.
